2
Pass IEC 61000-4 industrial Electro-Magnetic Compatibility (EMC) detection, thus
ready with strong anti-electromagnetic interference capability.
Support a Mean Time Between Failure (MTBF) of 35 years.
1.2.2 Rich product types
The SNR-S212i-8POE, with flexible interface configurations, can meet special industrial
environment requirements, with the following characteristics:
Provide 8 RJ45 electrical interfaces and 4 SFP optical interfaces.
The SFP optical interface supports 100 Mbit/s and 1000 Mbit/s optical modules.
Provide 1 RJ45 Console interface.
Provide 1 Phoenix-terminal external alarm output interface.
1.2.3 Powerful PoE power supply
The SNR-S212i-8POE supports PoE, with the following characteristics:
Support Endpoint PSE (PoE integrated in the SNR-S212i-8POE).
Comply with IEEE 802.3af standard (PoE).
Comply with IEEE 802.3at standard (PoE+).
Support standard PD and non-standard PD.
Provide 8 IEEEE 802.3af PSE interfaces or 4 IEEE 802.3at PSE interfaces.
Support enabling/disabling PoE and configuring maximum Tx power, power supply
mode, and power supply priority of a power supply interface through software.
Support overtemperature protection.
1.2.4 Flexible networking
The SNR-S212i-8POE supports flexible networking capabilities, with the following
characteristics:
Support chain, start, dual-star, single ring, intersecting ring, and tangent ring networking
modes.
Support Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and
Multiple Spanning Tree Protocol (MSTP), thus improving redundant backup and error
tolerance and ensuring stable network operation.
Support ITU-T G.8032 Ethernet Ring Protection Switching (ERPS) protocol. The
network self-healing time is less than 50ms. ERPS solves the multi-ring protection,
multi-topology, multi-domain protection, and multi-protocol problems.
Support a leading industrial Redundant Ring Protection Switching (RRPS), with self-
healing time less than 50ms
1.2.5 Strict QoS
The SNR-S212i-8POE supports static QoS technologies, with the following characteristics:
Support IEEE 802.1p QoS, thus providing the customer with reliable and effective
means for optimizing services.
Support interface trust modes, trusted Class of Service (CoS) priority, and trusted
Differentiated Services Code Point (DSCP) priority.
